There are already a number of digital TV(DTV) set-up box that you can buy right now from various brands and stores if you want to experience the clearer signal from your fave free TV channels. After I spotted some local and global TV brands capable to get in DTV signal out of the box, Samsung might also doing that move soon.
Thru one pic from FB user Jason Joseph Aquino from a DTV box-inspired FB group, you can see below that the global brand will gonna bring their UHD TVs with DTV which adds more convenience for those who want to make the switch
Unfortunately, no clue/s on the exact Samsung UHD TV model that will have that feature. This pic was taken from a print material in Ansons in Trinoma
